In kunena posting I want tobe sure from the method a normal user can send an email to the kunena forum:1-does he need to do anything beside attaching the picture to the mail ???? i.e does he need to put [qqqq.img] tage

2-does the plugin has a mailing list feature ,I.e new post sent automatically to the users

3-what if a guest send an email to the "email of the plugin",does the program ignore it ,post it ??
